Rapid land use change has take place in Wuhan, the largest mega-city in central China during the last decade. Remotely sensed imagery together with geographical information system have long been utilized to monitor spatial and temporal land use change. The aim of this paper is to find out the land use change and the trend of urban growth in Wuhan, China using satellite images. The Landsat TM image acquired in 1991 and the Landsat ETM image acquired in 2002 were used to monitor land use change in Wuhan. The images were geo-referenced according to Gauss-Kruger projection with Krasovsky spheroid, by using 1:50, 000 topographical maps. The image processing is implemented by using Erdas Imagine package. The RMS error has been controlled under the limit of 1 pixel. The geo-referenced images were classified as seven land use types: cultivated land, forest land, grassland, urban and villages, transportation, water bodies and barren land. Two land use maps were produced for each date. The geo-referenced, classified images were compared pixel by pixel to locate and quantify land use changes that took place from 1991 to 2002 period. The further change detection analysis in a later stage is performed in ArcGIS. The transition matrix was produced and the quantitative information on the size of land use change from one type to another was compiles. The results of study indicate that the conversion of land use from cultivated land to urban was prominent, the rapid urban sprawl has occupied lots of cultivated land and water bodies, the urban area significantly increased 30%, most of which are converted from cultivated land. these valuable cultivated land need careful protection by providing land use plans to guide urban growth going toward the right directions. The results obtained from this application also indicate that the use of satellite imageries is very useful for mapping land use changes, and the monitoring land use change is essential for land use planning and urban sustainable development.
